Passive Stains Drops, Flows, and Pools, results from gravity acting
Transfer Stains object coming in contact with existing blood stains
and leaving wipes, smears, or pattern transfers
Impact Stains blood projecting through air and usually seen as
splatters. (May also include gushes, splashes, and
arterial spurts.)
Gunshot Splatter Includes forward splatter from exit wound and
back splatter from entrance wound. Typically:
Forward is a fine mist and the back is larger, fewer
drops.
Cast-Off Results when an object sung in arc flings blood
onto nearby surfaces. Tail points in direction of
motion and the number of arcs can show minimum
number of blows.
, Arterial Spray Spurt of blood when a major artery is severed with
new pattern created each time the heart pumps
Expired Splatter blood from an internal injury mixing with air from
lungs being expelled through the nose, mouth, or
an injury to airways or lungs, forms a very fine mist
and some blood stains are latent.
Sharp Force Injuries (Stabbing) Less blood being deposited on the instrument,
smaller more linear patterns of stains
Blunt Force Injuries (Hitting or larger surface area will collect more blood,
Beating) producing drops of various sizes.
Gunshot Injuries Mist like splatter caused by bullets entering and
exiting a body.
Transient Evidence evidence that might be expected to degrade or
disappear within a particular time frame
Exsanguination Bleeding to death
Sharp Instruments Make incised wounds
Blunt Objects Produce lacerations (deep cut or tear in flesh or
skin)
Altor Mortis Cooling of body after death
How long Lividity Lasts 36 hours
Lividity Discoloration of the body after death. Takes
minutes to an hour
